This fifty state quarter folder has pockets where you can place in two of each state quarter (one Denver Mint and one Philadelphia Mint). Since it spans the years 1999 to 2009, it also includes pockets for two of each U.S. territory quarter (one Denver Mint and one Philadelphia Mint). I have had mine for several years now, and it has held up very well, with the exception of one rip which I had to tape up. Compared to the 1999 to 2008, quarter folder, it is much easier to put the quarters in their pockets in this one. (Which means that you can put the quarters securely in their pockets without the use of a hammer.) I would definitely recommend this quarter folder.
